And it relates to a drainage rail for allowing the water flowing to the side can be moved back to a predetermined place and the construction method of artificial turf using such a drainage rail.

Artificial turf is a grass made of synthetic fibers such as polyvinylidene chloride, polyethylene, polypropylene or nylon and is mainly used in sports fields. For the construction of artificial turf, the drain pipe is laid at a depth of about 60 cm underground to fill the rubble and compact it. Then, the sand layer is formed on the rubble to compact it. After that, the artificial turf is constructed by forming a hard base such as an asphalt layer or a concrete layer on the sand layer. If necessary, a nonwoven fabric may be provided on the sand layer or an impact absorbing layer such as a foam rubber mat or a rubber mat may be provided on the cured base layer. A concrete layer about 100 mm thick, which forms the base layer of the artificial turf, can be made such that a gradient or slope of about 0.5% is formed for surface drainage. If such a gradient is made on the concrete floor, the ball may flow along the slope during the race, or as the moisture in the center of the stadium flows towards the edge, the water may gather at the edges, causing a surface mismatch between the center and the edge. Therefore, it is necessary to induce the total drainage through the rear part of the artificial turf in addition to the surface drainage while minimizing the slope of the artificial turf surface so that the entire artificial turf is dried regardless of the position.

Figure 1a shows an embodiment of a drain rail according to the present invention.

Referring to FIG. 1A, the drainage rail 10 has an inlet which extends along a length direction in an empty column shape, a plurality of permeable balls are formed on the bottom surface, and is formed on the ceiling surface to allow the inside and the outside to communicate with each other ( 111 formed body; And a cap 12 that is removably coupled to the inlet 111.

The body 11 may be made of a material such as metal, glass fiber reinforced plastic (FRP) or plastic, and may have a pillar shape extending in the longitudinal direction and hollowed out so that water may be temporarily stored or flowed therein. have. In the case of a hollow rectangular column as shown in FIG. 1A, the body 11 may consist of a bottom face B, a side S, and a ceiling face T, and a plurality of drainage holes in the bottom face B. 112 can be formed. The drain hole 112 is to allow the water introduced into the body 11 to be absorbed into the ground, and to have an appropriate diameter in consideration of the area of the bottom surface B at regular intervals along the longitudinal direction of the body 11. Can lose.

A fixing wing 113 may be formed on the side surface S of the body 11 to allow the drainage rail 10 to be fixed at a predetermined embedding position. Fixing wing 113 may extend in the longitudinal direction along the side (S) may protrude in a direction perpendicular to the side, but is not limited thereto. The fixed wing 113 is for allowing the drainage rail 10 to be fixed at a predetermined position in the process of placing concrete when the drainage rail 10 is embedded. Therefore, the shape of the fixing blade 113 is not limited to the shape shown in Figure 1a may have a suitable shape that can support the wire mesh described below.

An inlet 111 having a function of allowing water to flow into the interior of the body 11 may be formed on the ceiling surface T of the body 11. The inlet 111 extends in the same direction as the extending direction of the body 11 and may be formed on a portion of the ceiling surface T. As shown in FIG. 1A, the inlet 111 has a gap between the two separation walls 114 having a separation distance at the center portion of the ceiling surface T upwardly and the gap created by the separation walls 114. It can be made in the form of being an open inlet connected to the interior of the. The spacing wall 114 extends in the same direction as the body and the degree of protrusion or spacing upward may be determined in consideration of the height of the entire body 11 or the width of the ceiling surface T. FIG. For example, the separation distance may be 1/10 to 1/3 of the width of the ceiling surface T and the protrusion height may be 1/2 in 1/10 of the height of the body 11, but is not limited thereto. As described below, the separation wall 114 does not necessarily protrude upward, but may protrude downward as needed. As such, the inlet 111 may be made in various forms and the form shown in FIG. 1A is exemplary and the present invention is not limited thereto.

When the drain rail 10 is installed and the concrete is poured, the concrete may be introduced into the body 11 through the inlet 111. In order to prevent this, a cap 12 for temporarily sealing the inlet 111 may be fitted to the inlet 111. If the inlet 111 has the shape shown in FIG. 1A, the cap 12 extends from the center of the cover face 121, the cover face 121, extending in the same direction as the body 11 or the inlet 111. Extending in the same direction as the protruding wall 122 from both ends of the protruding wall 122 and the cover surface 121, which may be fitted into the inlet 111 while extending downward and spaced from the protruding wall 122. ) Includes a pair of protective walls 123a and 123b with a gap such that they can be inserted. As described above, the cap 12 has a shape covering the entire inlet 111 by closing the inlet 111 and simultaneously forming a wall for protecting the separation wall 114 from the outside. The cap 12 thus protects the insertion groove 111 and the spacing wall 114 during the casting process of the concrete and at the same time the cap 12 is removed from the body 11 after the casting of the concrete as described below. As a result, a collecting flow path is formed.

As shown in FIG. 1A, the lower extension length of the protruding wall 122 may be smaller than the lower extension length of the protective wall 114. Specifically, the extension length of the protrusion wall 122 may be 1/4 to 4/5 of the extension length of the protective wall 114. This reduction in the extension length of the projection wall 122 is intended to allow the projection wall 122 to be easily separated from the inlet 111 with a small pressure in the process of placing concrete and removing the cap 12 from the body. will be. In the concrete pouring process, the inflow of concrete through the inlet 111 is substantially blocked by the protective walls 123a and 123b. Therefore, the projection wall 122 functions to prevent the gap of the inlet 111 from decreasing from the side pressure acting through the protective wall 114 in the concrete pouring process. In consideration of this, the protruding wall 122 may have an extension length that fits only at the upper end of the inlet 111. If the strength of the protective walls (123a, 123b) is a material having sufficient rigidity for the pressure acting laterally during the concrete casting process, the protrusion wall 122 may not be formed, but even in this case, the gap of the inlet 111 Since the size is difficult to ensure, it is preferable that the projection wall 122 is formed regardless of the material strength.

The shape of the cap 12 shown in FIG. 1A is formed to match the shape of the inlet 111. If the inlet 111 is of a different shape, the shape of the cap 12 will also have to be made different.

Figure 1b shows another embodiment of the drainage rail 10 according to the present invention.

Referring to Figure 1b, the body 11 is composed of a bottom surface (B), side (S) and ceiling surface (T) and a fixed wing (protruding outward of the body 11 in the middle portion of the side (S) ( 113) is formed. In addition, the plurality of drain holes 112 formed on the bottom surface B are similar to those of FIG. 1A.

In the embodiment shown in FIG. 1B, an inlet 111 is formed by two separating walls 114 extending downward from the ceiling surface T and a cap capable of sealing and protecting such an inlet 111. 12a) is different from the embodiment of FIG. 1a in that it is formed. The two separation walls 114a extending downward from the ceiling surface T have a function of preventing the inlet 111 from being closed due to the pressure acting on the side while inducing water flowing into the body 11. Can be. Therefore, two separation walls 114a may not be formed as necessary.

The cap 12a, which seals the inlet 111 and forms the collecting channel, extends in the extending direction of the body 11 and has a bottom surface of the protective plate 121a and the protective plate 121a having a thickness suitable for forming the collecting channel. It includes a sealing protrusion (122a) that protrudes downward from the fitting can be fitted to the inlet (111). The protection plate 121a may extend in a rectangular plate shape with a constant thickness and the extension length may be appropriately determined by the depth of the concrete layer and the formation position of the collecting flow path. In addition, the sealing protrusion 122a having a shape extending from the bottom surface of the protective plate 121a to be inserted into the inlet 111 may extend to any length, but is preferably longer than the extension length of the separation wall 144a. It can be extended shortly. As described in connection with FIG. 1A, the cap 12 must be removed from the body 11 after casting of the concrete, so that the sealing protrusion 122a is fitted with slight pressure to the inlet 111 and is easily pulled out by gravity after casting. The thickness and extension length can be determined so that they can be separated.

As described above, the inlet 111, which is a passage for introducing water from the outside into the body 11, may have various structures, and the cap 12 may collect water while temporarily closing the inlet 111. It can have any shape which can form a flow path. 1A and 1B are exemplary for the body 11 and the cap 12, the present invention is not limited to the embodiments shown.

Hereinafter, the construction method of the artificial turf to which the drainage rail 10 according to the present invention is applied will be described.

2B and 2C illustrate an embodiment in which artificial turf is laid by a construction method according to the present invention.

2B and 2C, in order to install artificial turf, a concrete layer (C) is formed on the foundation layer (G), and an uneven drainage induction path (R) is formed in the concrete layer (C) and the concrete layer. Artificial grass (P) can be installed on (C). The foundation layer (G) can be made of aggregate that easily passes water down, for example gravel or crushed stone, and if necessary, an elastic layer made of an elastomer such as silica or rubber is formed on top of the concrete layer (C). Can be. Artificial turf may also be installed on a substrate M, such as a nonwoven fabric.

The uneven drainage induction path R formed in the concrete layer C may be a grid shape NS shown in FIG. 2A or a circular grid shape CS shown in FIG. 2B. The drainage induction path R may be formed by (i) a concave-convex roller, (ii) by embedding lattice-like hardware, or (iii) by using a concrete knife.

FIG. 3A illustrates an embodiment of the uneven roller 30 for forming the uneven drain induction path R. As shown in FIG.

Referring to FIG. 3A, the uneven roller 30 has a cylindrical shape, and a gradient protrusion 31 is formed on the surface in the longitudinal direction of the cylinder. The gradient protrusion 31 means that the inclination of 0.3 to 0.8% is formed centering from both edges of a cylinder, for example. The inclined direction can be shaped such that the radius of the cylinder is small at the center and the radius of the cylinder is large at both edges. In order to form the concave-convex pattern by the concave-convex roller 30, a drain induction path R connected to the inlet 111 of the drainage rail 10 embedded in the concrete layer C may be formed as shown in FIG. 3B. Position the uneven roller 30 so that it is. And when the concave-convex roller 30 is rotated along the upper surface of the concrete layer (C) in the semi-hardened state before the concrete layer (C) is cured, the concave-convex shape that can communicate with the inlet (111) by the gradient projections (31) Induction furnace (R) may be formed.

Another way to form the uneven induction drainage (R) is to take out the surface of the concrete layer (C) in a state before the uneven shape is cured into an embossed plate. As described above, the induction drainage R having an uneven shape may be formed in various ways, and the construction method according to the present invention is not limited by a specific method of forming the induction drainage R.

The unevenness of the lattice hardware may be formed by the following method.

3C illustrates an embodiment of the grid metal 30a for forming the drainage induction path R having an uneven shape.

Referring to FIG. 3C, the grid hardware 30a may be formed of a gradient grid 32 disposed at regular intervals along the horizontal and vertical directions. Each plate forming the gradient grid 32 can form a lower gradient than the center portion at both ends, and the degree of the gradient can be 0.3 to 0.8%, similar to the gradient projection 31. The grid-like hardware 30a may be installed to be connected to the inlet 111 of the drainage rail 10 before or after the concrete is poured. After the concrete is completely poured and the grid-like hardware 30a is removed before the hardening of the concrete, the drainage induction path R connected to the inlet 111 may be formed by the gradient grid 32.

Another method of forming the uneven drain induction furnace (R) is to use a concrete knife. After the concrete layer is completely cured, an uneven drainage induction path R having a gradient connected to the inlet 111 of the drainage rail 10 may be formed using the concrete knife.

As such, the uneven drainage induction path R may be formed in various ways, and the construction method according to the present invention is not limited by the degree of gradient or the shape of the drainage induction path R. FIG.

In order to install artificial turf in the form shown in FIGS. 2A and 2B, a foundation layer G is first formed. The method of forming the foundation layer G may be in any form known in the art. If necessary, the drain pipe may be embedded in the foundation strata G, but is not necessary.

When the foundation layer G is formed, the position where the drainage rail 10 is to be installed should be determined (P21). Drain rail 10 may be installed in consideration of the shape in which the induction drainage (R) is formed at regular intervals (P21). The drainage rail 10 is installed in a state in which the cap 12 is coupled and is installed to closely contact the bottom surface B with the base ground layer G so as to prevent displacement from occurring in the vertical or horizontal direction.

When the drain rail 10 is installed (P21), a fixed wire mesh 41 as shown in FIGS. 4A and 4B may be installed on the drain rail 10 (P22). The fixed wire mesh 41 prevents the drain rail 10 from changing its position during the concrete pouring process while connecting the drain rails 10 to each other. When the drain rail 10 and the fixed wire mesh 41 are joined by welding or other fixing means or other metal, the drain rail 10 is fixed at the installed position and can be prevented from shifting position after pouring or pouring concrete. have. The fixed wire mesh 41 is not necessarily installed and may not be installed as necessary. Alternatively, the drainage rails 10 may be connected to each other, for example, by means of an inset or a fixed bar. The fixed wire mesh 41 may be installed on the fixed blade 113 of the drainage rail 10. As described above, the fixing blade 113 has a function of fixing the position of the drainage rail 10 in the different concrete in the protruding shape while positioning the fixing wire mesh 41 at a predetermined depth inside the concrete. In addition, the fixing wire mesh 41 and other means such as welding or the like so that the drain rail 10 can be connected to each other as a whole through the fixing wire mesh 41. If the fixed wire mesh 41 is installed (P22) concrete can be poured (P23). Concrete can be of any shape known in the art. Uneven and poured concrete can be formed as described above before the hardened concrete cures. If drainage guideways are formed using concrete knives, relevant work can be done after the hardening of the concrete. On the other hand, before the hardening of the concrete, the cap 12 is 10 from the drainage rail 10 (P24). The drain induction path R from the cap 12 can be connected to the cap 12 or other formed catchment flow path or inlet. 0) of the cap 12, the catchment flow path is made on the upper surface of the concrete, and when the concrete is hardened, the upper surface of the concrete is cleared and the drainage is established (P25). Can be done using a tool such as a concrete knife to adjust the gradient of the drainage guideway R while making the cross-sectional area of the inlet or catchment flow path uniform. Artificial turf can be laid on top of concrete layer (P26) Artificial turf can be laid using nonwoven fabric and elastic layer can be installed between concrete layer and nonwoven fabric if necessary.

According to the present invention, the construction method of artificial turf enables the drainage to be made smoothly in the entire artificial turf through the uneven drainage induction path, while reducing the degree of gradient between the central part and the edge, and thus the sense of artificial turf. This has the advantage of being able to prevent the change from place to place. In addition, it is advantageous to allow the artificial turf to be dried in a short time by allowing the drainage to be made quickly through the drain rail.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it will be understood by those skilled in the art that various changes and modifications may be made without departing from the spirit and scope of the invention .
